Heat Conductivity Test of Carbon Fiber Sandwich Panel with Flame-Retardant Core

This article addresses the burning test conduct on two different configuration of carbon fiber panels comprise with same fiber and resin, one as pure laminate and the other as sandwich panel, subjected to flame fire using a standard propane-air burner [1]. The aim is to evaluate the behavior of heat conductivity between specimens with and without flame-retardant core. The tests were performed on a specific designed burning framework with standard size specimens held right on the top of the flame and burn for a minimum of time. The test result indicates that, specimen with flameretardant material as sandwich core has almost four times heat resistance than pure laminate panel. In addition, a major difference of residual mechanical properties between two configurations were also observed.
